Serial No. 221,543.

Our invention relates to typewriting or like machines and more particularly to work 'ing and collating in the machine various combinations of work sheets for bookkeeping, billing and other work.

One of the main objects of our present invention is to provide improved means of the character specified which facilitate a carrying out of the work with great rapidity, with little chance for faulty operation on the part of the operator, with an assurance of mechanical accuracy in the collating operation and which require but a few simple opera tions, free in the main from the exercise of judgment, in order to properly manipulate the machine.

The present invention is in the nature of improvements onthe so-called Remington front feed bookkeeping machine, and on a machine such as is disclosed in the application of Sigurd L. Walsoe, Sr. No. 195,321 filed May 31, 1927 (now Patent No. 1,714,063

" dated May 21, 1929) lh'e present invention is intended to improve such machines by widening the scope of their uses; to provide for a ready adjustment of variousparts that enable the machine to be more readily employed on work sheets of various widths; to

provide a construction in which fewer operations are required to manipulate the machine and in which the'proper relation of the parts required at certain times is attained with less efiort on the part of the operator and with a greater assurance of accuracy than formerly, and in which virtually a universal billing mechanism of the character specified is provided.

To the above and other ends which will hereinafter appear, our invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

said feed Figure 13'is. a detail, fragmentary plan view of the construction disclosed in Fig. 12. .As in the said Remington machine and 1 alsothat disclosed in said previously filed application, the present machine is capable ofja wide range of uses in connection with various} so-called billing operations and the like,where two or, more work sheets are to be'correlated and printedjat a single operation. However, we do not deem it necessary todescribe specifically the many different forms of billing operations inwhich the ma chinemay be used. It isvsuificient for an "'understanding of the: present invention to specifically'describe one mode of billing that may be successfully carried out with the aid of the present machine, and perhaps briefly refer to some of the various other methods in connection with which the machine may 7 be employed.

One method of using thefmachine, which will be specifically referred to,,is its employ- 'ment,for simultaneously, or at one writing,

making. out a bill or statement, making corresponding entries on the ledger sheet carrying the account, and on a recorder register sheet whichreceives the various entries written on allof the individual statement and ledger sheets. Inv the example referred to theregister sheet and its accompanying carbon sheet remain in the machine. Meansare provided to enable the ledger sheet aand its accompanying carbon sheet to be quickly introduced; and properly positioned to receive the requisite entries without disf turbing the previously introduced register sheet and companion carbon sheet. Means also are provided for then quickly entering astatement sheet into the machine in front of the platen and accurately positioning it in proper correlation with the previously introduced ledger sheet and the printing line. The entries may then be made on the statement sheet and these will be transferred through the interposed carbon sheets to the ledgerand register sheets. Ifdesired, additional'entries may be made on the ledger sheet which are not to appear on the statement or register sheet. The statement and ledger sheets are then rapidly withdrawn from the machine without disturbing the register sheetand its companion carbon sheet and another ledger sheet and statement sheet may then 'be quickly introduced, as before,'

and so on.'

A line spacing operation effected by the return of the carriage after writing a statement and making the corresponding entry on the ledger and register sheets, advances the register sheet in position to receive a manifold .copyof; jthe neXtyent-ryon the register sheet. a I r With the foregoing general explanation of the purpose and operation, we will proceed to describe the invention as it is embodied, in

the present instance, in said hereinbefore mentioned Remington machine.

Theframe of the machine includes the usual top plate l supporting fixed guide rails 7 2.. The carriage or truckcomprises front and rear guide or crossbars 3,united by end bars 4 and 5. The guide rails 2 and cross barsB are oppositely grooved to receive crossed antifriction rollers 6 by which the carriage is sup ported in the usual manner to travel from side to side of the machine over the top plate 1.

A"cylindric al platen 7 ismounted in the surround it, against the upper case limiting stops 12. f This brings the printing line on the platen to a positionwhere the uppermost types on the usual type bars will register therewith.

, A ribbon vibrator 17 is mounted to slide up and down in theusual manner on a type bar center guide 18 secured to the type barsegment 19. The vibrator is actuated at each (see Fig. 6) which includesan arm 20. Said arm is pivoted at 21 ona shiftable carrier or printing operation by the usual mechanism support 22 mountedon parallel links 23. A

contractile spring 24 tends to lift the shiftable' support 22, and causes an anti-friction roller 25 carried thereby to bear upward against the lower edge of a bar 26. This bar is secured to the carriage and extends substantially throughout the length thereof. In the standard Remington machines the purpose of this construction is to cause the ribbon vibrator to be shifted up and downwith the platen in the case shifting movements of the latter. .In the,

present construction there is no such case shifting movements of the platen but the construction, nevertheless, lends itself to the accomplishment of another'result which will hereinafter appear. I v

As in the construction disclosed in said siderable height above the platen.

previously filed application it is desirable when introducing a work sheet backwardly into the machine to lower the ribbon vibrator from its normal, Fig.1, position. This is in order to enable the front paper deflector to be more convenientlymoved to effective position, as shown in Fig. 3. In the present construction we have employed the same means that are disclosed in s id hereinbefore mentioned application for effecting this result. Thus, as in the prior construction, a bracket arm 27 extends forward from the shiftable support 22 and carries an anti-friction roller 28 at the upper end thereof. A rock shaft 29 extends throughout the length of the carriage and is mounted at its ends in bearing openings in the end plates, 8 and 9 of the platen frame. This rock shaft 29 carries a plate 30 which extends substantially throughout the length thereof and is bent down at its forward edge to form a flange 31 which coacts with the anti-friction roller 28. When the rock shaft 29, and the plate 30 carried thereby, are shifted by means to be hereinafter described, from the Fig. l to'the Fig. 3 position, the shiftable support 22 will be lowered against the power of its spring 2 effecting a corresponding loweringof the ribbon vibrator 17 from its normalposition.

Coming now to the means for controlling and guiding the work sheets,.it will be observed in the first place that there are no paper feed. rollers employed beneath the platen, such rollers as are employed being located above the printing'line, leaving the space beneath the platen free for the use of other devices.

As in said prior constructions there are two curved paper deflectors 32 and 33 em ployed beneath the platen, one arranged above the other and maintained spaced apart by intermediate spacing members or blocks 34 and 35 located near the ends thereof. Generally speaking, these deflectors conform to the curvature of the platen or are substantially concentric therewith and extend substantially throughout the length of the platen. As thus constructed there are two separate channels provided, one of which is the open channel 36 between the two deflectors and which is bounded at its ends by separating members 3d and 35, either or both of which may constitute side guides or gages for cooperation withv a work sheet or sheets introduced'into the channel 36. The other separated channel 37 is provided between the under surface of the platen and the upper deflector 32. The forward elge of the deflector 33 terminates in advance of the for ward edge of the deflector 32, and has a slight downward curve in cross section. The deflector 33 is continued up at the rear to pro vide an upwardly and rearwardly extending paper table 38 which terminates at a con- On the other hand, the deflector 32 terminates in the rear of the platen at a much lower point and below the top of the platen, where it is bent to form a loop 39 that loosely surrounds a rod 40 fixedly connected at its ends to the end plates 8 and 9 of the platen frame. In this manner the rigidly united deflectors 32 and 33 are mounted on the rod 40 and have a slight controlled pivotal movement thereon.

Suitable adjustable means, which for the purpose of the present invention it is unnecessary to describe, may be employed to hold the double deflector 3233 against pivotal movement around the rod tO and with the front edge of the deflector 32 arranged close to the platen, as shown. In this inanner the sheets introduced from the rear of the platen through the channel 37 will be held snugly against the platen, and the sheets introduced into the channel 36 will be prevented from entering the channel 37.

In order to facilitate the backward introduction of the work sheets into the mouth of the channel 36 from 111 front ofthe platen,

there is provided a guide, shield, or front Iu paper deflector 47 that is movable on the carriagefrom a substantially horizontally dis posed ineflective position, shown in Fig. 1, to a downwardly and rearwardly lncllned eflective position, shown in F1g. 3, and vlce versa, as disclosed in said previously filed In order to receivethese moveapplication. ments the deflector is constructed and mounted, in the present instance, in the specific manner disclosed in said previously filed application. v

Thus the sheet metal deflector 47, which extends substantially throughout the length of the platen, is carried by parallel sheet metal supporting arms 28 and 49. These supporting arms are pivotally mounted on forwardly projecting arms 50 secured to the end plates 8 and 9 of the platen frame and which may be regarded as parts of said end plates.

The left-hand pivot pin 51, on which the arm 48 turns, supports a bell crank lever 52 one arm of which carries a pin 53 by which a detachable connection is made with the arm 48. The other arm 54 of the lever 52 carries an outwardly projecting connecting pin 55 that is received and works in'a slotted cam 56 in an actuating arm 57. Said arm 57 is provided with a hub 58 (see Fig. l) by which it is secured to the hereinbefore mentioned rock movementof the deflector 47 it passes from aposition where it isout of the path of the typebars to a position whereit'is'in the path thereof, and crosses the printing line ,where it is effective in directing work sheets introduced rearward from in front of the platen downward into the open channel 36. From thence the sheets in question pass 7 around and beneath the platen. f

The actuating arm 57 is provided with a so-called secondary or auxiliary finger piece 59 at the upperend thereof, whereby said two supporting arms for a wire line-indicator 60. Said indicator extendslongitudinally throughout the length ofthe platen and is adjustablyconnected to the arm 57' by means of two clamping jaws 61 and "62, as disclosed in said a prior application.

' The oppositeend of theline indicating wire may be adjustably' secured to a second supporting arm 63' (see' Fig. 1), the arm 63 being securedjto the rock shaft 29 near the right-hand end thereof. A coiled con-, tractilespring 64 is connected at one end to the arm 57 andatits opposite end to a pin 65 extending inward fromthe end plate '8.

35 This spring tends to return the arm 57 and the parts connected therewith to the normal,

Fig; 1, position. 3

The'paper feeding mechanism embodied in the present construction includes a plurality offlaligned paper feed rollers 66, arranged to coact with the top ofthe platen and with work sheets introduced from the remof the platen through the channel 37.

- "Said feed rollers 66 coact with said sheets after the latter have p assedabove and beyond the printing line. The paper feed rollers 66,. as shown in the present instance, are constructed and mounted in the same general manner as in said hereinbefore mentioned application. Thus, the feed rollers are mounted for longitudinal adjustment along a supporting rod or spindle 67, supported at its ends by forwardly extending arms 68 that are 'pivotally supported on the platen frame. Springs 68* exert their force against the arms 68 and thus cause the feed rollers 66 to bear against therplaten, or certain only of the work sheets thereon.

G0 are released; r

In the present machine we have included certain novelafeatures relating to mounting adjusting and controlling the front paper feedroller and also have included certain of the'means disclosed in said prior application thatis substantially T-shaped in cross sec.-

'front cross bar 3 of the carriage." In this By swinging the spindle 67 V upward and rearward the said feed rollers by which the paper deflector, line indi cator '60, the ribbon vibrator 17 and end stops are automatically controlled thereby.

In some. instances, we have modified such mechanism, and in other inst'ances'we'have combined therewith new features, as will now -be described.

r In the n present construction we'have rovided a pair, of outside margin paper eed rollers 69 and one or more inside or intermediatepaper feed rollers 70 which coact with the platen above the printing line. Each of these feed rollers is constructed, mounted and controlled in part in alike manner, and the description of one such feed roller and its mountingand control will apply to the others, except as hereinafter'specifically pointed out. Referring more particularly to Figs. 7,8 and 9, it will be seen that each of the feed rollers 69 and 70'is mounted to turn on a pivot 71'received between and riveted to two parallel roller carrying arms orslides 7 2. Each pair of slides 72 thus connected are supported for rectilinear movement fore and aft of the machine by and between a pairof supporting arms 73.

In accordance with the present invention each of the supporting arms 73 is pivoted to turn on a rock shaft Hand is confined within a guide slot between two'companion brack- "etarms 7 5 that project up. from a support or bracket 76 substantially C-shaped in cross section at the base thereof; Thi's'support is mounted onthecross head 77 of abar 78 tion and extends substantially throughout the length of the carriage in fron'tfof the platen. Screws 79 secure the bar 78 to the manner each support 76 together with the parts carried thereby is mounted for adjustment as a'single'unit longitudinally of the.

bar 78. This is in orderto provide fora separate adjustment of each of the feed rollers 69 or 70 together with'the controlling 1 10 members' associated therewith to different points longitudinally of the platen, and thereby adjustsuchparts for use with various widths of ledger'and invoice sheets and I to the different positions" lengthwise of the and bears at its front end against the face of the cross head 7 7 By loosening ajscrew 80 the companion bracket 76 is freed for lon gitudinal adjustment along the bar 78.

It has been hereinbefore pointed out that I each'of the supporting arms 7 3 is pivotallv supported at its frontv end on the'rock shaft 7 4, which in turn is-supported near its ends for rocking movement by bracket plates 81 f and 82, secured by screws'83 to the carriage,

as indicated in Fig. This rock shaft is held against longitudinal.displacement by a col-I lar 8e: held'by a set screw 85 on said shaft outside the bracket plate 82 and by a hub 86 held on the shaft by screws 87 and 88 outside the bracket plate 81. The hub 86 has an arm 89 secured thereto, said arm terminating in what may be termed a main or primary finger piece 1 90 by which the shaft 74 may be rocked to control the feed rollers 69 and 70 and other parts in a manner which will hereinafter appear. Each of the supporting arms 73 has :1

depending arm 73 (Figs. 7, 8 and 9) provided with an inwardly ear 91 so that each member comprising the parts 73, 73 and 91 is in the nature of a bell crank lever pivoted on the rock shaft 7 1. Each ear 91 is apertured at 92 to loosely receive therethrough a headed pin 93 which. is in the na-' 1 ture of a shouldered andheaded screw received at its threaded end in a tapped opening in the base of the companion bracket 76. A. rather heavy coiled expansion spring 9-1'surrounds each pin 93 and bears at one end against the head of the pin and at the other end againstthe rear face of the companion ear 91. The force of each pair of springs 9% 1s 7 thus exerted to forcethe associated ears 91 against the base of the companion bracket 'Z'6,

as shown in 8, and thus said springs tend to hold the companion and connected pair of supporting guide arms 73 against pivotal movement around the rock shaft 1 until the force of saidsprings' is overcome in a mandered stem of each of the guidepins 96 passes loosely through a circular opening in the asn her which will presently appear.

therethrough, and thus support and guide each arm 72 at its forward end. The shoulsociated arni'l'Qand is riveted at its inner end to one end of a toggle arm 98. The other end of each toggle armor member 98 is pivoted; at 99 toone end of a companion toggle arm or member 100 or 101, such toggle arms for the outside feed rollers 69 being designated as 100, whereas such toggle arms'for the intermediate feed rollers 70 are designated by the reference numeral 101. As shown in Fig. each of the toggle arms 100 for the feed rollers 69 has a projection or spline 102 that is received in a substantially V-shaped spline groove 103 in the rockshaft 71. By these means the toggle arms 100 are all connected to rock with the shaft 74 without, however, interfering with the adjustment longitudinally of said shaft, of the associated supports 7 6 and the parts carried thereby, including the arms;100.- From an inspection of F 11 it will be-understood that each of the toggle arms 101 for the intermediate feed roller or rollers has no splined connection with the rock shaft 7 4 but has a pivotal bearing thereon so that said armslOl are free to turn on the shaft independently thereof, and the shaft is free to be rocked without rocking said arms.

ion arms 100, or 101 as the case may be, constitutes a tie rod between the two sets of toggle arms for each feed roller 69 or 70 and causes them to move together. Each pair of g I t will be seen that the pivots 99. uniting the toggle arms 98 withthe compan toggle arms 101 are, however, further united by cross rod 104, which constitutesa finger piece by which the companion toggle members 98 and 101 may be moved from the bro ken (Fig. position to the substantially straight-line position indicated in Figs. 1 and 9 to separately apply each of the feed rollers 70 to the platen.

From what has been said it will be understood that a rearward movement of the finger:

rollers coact. During this movement of the feed rollers 69 the springs 94 will maintain the guide arms 73 against pivotal movement around the rock shaft 74:. lVhen, however, the feed rollers 69 reach the curved surface of the platen they will be forced by the further straightening togglesto ride up on the platen a short distance, the curved surface of the platen at; this time acting as a cam.- The effect of this is that the guide arms 73 will receive an upward swinging movement around the rock shaft 74 against the resisting force of the springs 94. The reaction of said springs at this time willforce the rear ends of the guide arms 73 down and apply the feed rollers 69 to the platen with aspring pressure, while the toggles are maintained in a substantially dead centerposition and prevent a breaking of the toggles until the finger piece 90 is moved forward. In practice it is preferable to shift the toggles slightly past the dead centered or straight line position where they are arrested by stops 105 on the arms 7 3. It will be seen, therefore, that the feed rollers 69 are applied to the platen with a strong spring pressure exerted only after the feed rollers reach the platen and when the guide arms 78 receive a pivotal movement due to forcing the feed rollers to ride on the curved surface of the platen dur ing the final portion of the straightening of the toggles. As above indicated the feed rollers '69 are simultaneously withdrawn from the platen to a considerable'distance a manners may be separately applied.

- il y introduced intothe channel 36 -frornin front of thefplatenl Thefeedrollers-70 are applied the same manneras that, above described except that e8h.feed;rolle,r- ;70 is separately applied, in

the construction as thus far described,byan

' independenti actuation of each of the finger pieces 104. The purpose of this individual application ofeach of the feedrollers70,in

' some instances, will hereinafter appear.

"It is desirable to automatically withdraw theintermediate feed rollers 70 with 7 the outer feed rollers 69, whetherone or more intermediate feed rollers'be employed, and whether, ornot each of a lurality of intermediate feedirollers 70 e separately applied. fTothis end we provide for each feed roller 70' a crank or actuating arm 106 (see' Figsf 8 and '9) that extends rearwardfrom va 107, that surrounds the rock shaft 7 4,

intermediate associated bracket arms of the companion carrier 76'. This hub is a tapped to receive two pointed screws 108 and 109,.the ends of which extend intothe spline groove 103 of the rock' shaft, the screw 108" coacting with one inclined side wall of the groove, and the other sorew109 ooactinglwith the opposite inclined wall of I the groove, as shown in Figs. 8 and 9. By

- this construction a backing up of one screw aithreading, in of the other screw. will effecta rotative' adjustment of the associated 7107,; thus elevating or depressing the companionqactuating arm 106. This brings the rear end of theactuating arm, which underliesthe companion tie rod 99 closer to or further from saidjrod and thus regulatesor times Ithe breaking of the associated toggles by the actuating-arm 106 as the latter iselevat'ed from'theFig. 1 position by a forwardmovement of the'fi'nger piece from the Fig. 1 to theFig. 3 position. The result of thismovement of the finger piece 90 is to Y efiect a,clockwise movement of the shaft 7 4 causinga withdrawal of all of the feed roll-.

together with all of the actuating arms 106,

' ers 70 simultaneously with the withdrawal of the fejed rollers .69, notwithstanding each ofg ltwill be understood, of course, that a tightening of'both screws 108' and 109 after thorequisite adjustment of the associated arm 106 has been attained will i hold the hub and arm firmly on the shaft 74: against, both rotativeand longitudinal movement thereon. When,however, a feed roller 69 01-70 is to be adjusted logitudinally ofthe platen, a slight baclring up ofone of the associated screws 108 or; 109 will release the hub107; and its armfor adjustment along the shaft 7 4 with the associated support 76 and the other parts carried thereby, so that all of suchfparts ma be adjusted as a single unit. Afterthea justment last mentioned has been'attained' the loosened screw 108 or 109 will be again tightened and the partswill be ready for use.

The hub 86 to which thearm 89 and finger iece. 90 are secured is connected to the shaft.

, 4 by the two screws 87 and 88 in the same ,1

manner that each pair ofscrews 108 and 10 9 connect the campanion hub107 tosaidi shaft. This manner of connecting the hub 86 to the shaft provides foreffecting a rotative adj ustment of the arm 89 to different set positions on the shaft and consequently regulates or times the actuationof other parts controlled by said arm, and which will be presently described. Said means for connecting the arm 89 to the rock shaft also enables, it to be I readily placed on the shaft and to be removed when desiredas, for example, when the shaft is to be removedand one of the carriers76 for an intermediate feed roller 7 0, together with the parts carried thereby, is to be re-' moved from or placed in position on the shaft. In this connectionit "will be'understood that in some instances a single intermediate feed roller 7 0 and associated parts may beemployed, although there is rovided a wider range ofuse when a plura ity, say, two feed rollers 70 are employed asshown, as willpresently appear. i 7

We employ in the present construction automatically controlled paper end stops, such as are disclosed in said prior application, and which are intended to coact with the bottom edges of a rearwardly introduced bill sheet and the accompanying carbon sheet introduced inpthe channel 36. "While the;

stop construction is, the same as disclosed in said prior applicationtherejare employed in. the present construction novel means for.

automatically controlling said stops. Such stop construction will nowbe described. I We refer to employ two automatically control ed end stops, though. any suitable number may be employed. Inasmuch as each of these stops is mounted, adjusted and controlled in a like manner the description of one' will apply to both. A supporting strip 112 which is preferably made ofspring tal; is secured by suitable means to the back of the paper. table 38near the upper end fthereof. The supporting strip 112" extends J down in the rear of-thepaper table and has its; lower end portion curved at 113 to'conform generally tothe curvature of the paper deflector 33. This curved portion of the supporting strip has a slot 114, as best shown in' Figs. 3 and 5, :that extends lengthwise thereof and fore and aft. of the machine. paper end stop 115,- in the nature of a pin, is provided with a reduced, threaded, shank or lore and aft of the machine in a curved path around,

the platen, such path conforming generally to the curvature of the deflectors 32 and 33 and the intermediate channel 36 between them, and into and out of which channel the stop moves in any position to which the stop may be adjusted. After the stop has been adjusted on its carrier to the desired position, a tightening of the nut 117 will secure the stop in place thereon. The means just desc ibed affords a rather wi le range of adjustment of the stops to accord with bill sheets, checks, etc. of different depths.

The supporting strip 112 has off-set from one side of the lower portion thereoi a depending finger or arm 119, as best shown in Figs. 3-and 5. This arm projects into the path of a finger 120 secured to a crank arm 121, the hub 122 of which is securedby a set screw 123 to arock shaft 124.

1 is shaft extends throughout the length of the carriage and has reduced ends received in bearing openings in the end platesS and 9. lVhen the shaft 12a is turned clockwise in Fig. 1, the stop 115 is withdrawn to the ineffective, Fig. 3, position against the spring force of the stop-carrying spring strip. When the shaft 121 releas d a light spring tends to return said sha tto normal position, thereby enabling the stop 115 to be projected by its sprin carrier to the operative, Fig. 1, position. v

It will be understood that in the present instance we have provided two end stops 115 and companion supports and releasing devices therefor. These stops are ali ned and located at a distance apart such as is re quired to coact'with and arrest the comparatively narrow bill and carbon sheets B and B respectively and accurately gage them.

The rock shaft 12 1 by which stops 115 are controlled is itself controlled by the following means: I

A crank arm or actuating arm or member 126 has a hub 127 secured to the rock shaft 121 by a set screw 128. This member is substantially U-shaped in outline so as to pass around the platen shaft and provide a contact edge or stop 129 which normally coacts with the collar or hub 130 on the left-hand platen head to arrest said member and the parts controlled thereby in normal position, as shown in Fig. 1. Asecond contact edge or stop 131 on the member 126 coacts with the opposite side of the hub 130 to limit the movement of the member in the opposite direction, as shown in Fig. 0. The upper arm of the actuating member 126 is slotted longitudinally at 132 to receive a headed pin 133 on the rear end of a link 1341. The forward end of the link 13 1 is pivotally connected to a headed pivot pin 135 riveted to a second link 136 which extends forward and upward where it makes pivotal connection at 137 with the arm 89. The pivot pin 135 in extending from the link 136 to the link 13 l'passcs through a guide slot 138 in a rear extension of the bracket plate 81. Said bracket plate in addition to being secured to the carriage by a screw 83 is connected thereto by a supporting link 139 supported at its lower end on the pivot pin 51. It follows from the foregoing that the point of pivotal connection between the links 13 1 and 136 will be guided the pivot pin 135 working in the slot 138 to movein a straight line fore or aft of the machine when the finger piece 90 is actuated, depending on whether said finger piece is moved forward or backward. It also will be understood from an inspection of Figs. 1 and 5 that a spacing sleeve 140 which surrounds the pivot pin 135 constitutes an abutment or contact device that in the movement of the feed rollers under control of the finger piece 90 to ineffective position, or from the Fig. 1 to the Fig. 3 position, will engage the arm 57 and shift it and the parts controlled thereby. This results in automatically lowering the ribbon vibrator 17, in shifting the line indi cator 60 from effective to the inefiective, Fig. 3, position and in shifting thefront deflector 17 from the inefiective to the effective, Fig. 3, position. In addition to this, this same movement of the finger piece 90 results in moving the link 13% forward and, after a preliminary extent of lost motion, picking up the arm 126 and shifting the stops 115 from the effective to the ineffective Fig. 3 position. This automatic shifting of the end stops 115 to ineifectivejposition when the feed rollers 69 and are withdrawn and the machine is otherwise conditioned to receive a rearwardly introduced comparatively long and wide ledger sheet L, is in order to allow the bottom end of the ledger sheet to pass rearwardly beyond said stops. The extent to which the ledger sheet may thus be introduced past the end stops may be determined by registering a given portion or line ofthe ledger sheet with the line indicator 6O ormay be determined by special end stop mechanism such for example as that disclosed in the application of- Frederick Hart, Sr. No. 172,685 filed March 1, 1927. It should be observed that when the feed rollers 69 are applied to the platen the arm 126 may be actuated at will by a finger pie e 126 carried thereby to movethe end stops 115 to inefiective position. This is occasionally required when, for example, the end stops 115 are adjusted for use in gaging comparatively short bill sheets and it may be necessary now and then to introduce a longer or deeper bill form. By temporarily holding the end stops 115 in ineffective position by the finger piece 126*, the longer bill form may be 6 introduced past theend stops 115 and gaged with reference to the printing'line and the previously introduced ledger sheet with the aid of the line indicator 60.v After the ledger sheet has been introduced and adjusted a 1 shifting of the finger piece 90 in the reverse direction will'restore all of the parts except the feed rollers 70 (which must be independently applied) to" the Fig. 1 position- It will be understood, however, thatwhen the partsare in the Fig. 1 position, thefinger piece 59 may be independently actuated to shift the deflector 47, the line indicator and the ribbon vibrator '17 to Fig. 3 pos1tion while the stops 115 remain in eifective posi- 7 tion, and that such shifted parts will remain in shifted position only as long as the opera.- tor holds the finger piece 59 against the force of its returning spring 64. This is in order that the machine may temporarily be conditioned to receive a comparatively nar-.

row bill sheet B, anditsaccompanying carbon sheet B in the channel 36, and enable them to be'properly gaged and positioned bythe end stops 115. while the feed rollers 69 remain in clamping engagement with the previously introduced wider ledger sheet L and hold itagainst movement. When this is effected therfeed roller or rollers 70 are ap plied, holding the bill sheet inposition. The fmachine is then in condition to proceed with the writing and a single written entry'will appear in appropriate positions on theproperly correlated bill sheet, the ledgersheet and the register sheet, the entries on the last two sheets being manifold copies produced with the'aid of the carbon sheets B" and R.

It sometimes occurs that a-narrow strip or bill sheet should have two separate entries written thereon, say for example, one directly I under another and that these entries should appear onthe ledger and record sheets, at different places wijdthwise of each ofthese two last mentioned'sheets. By providing, say,two independently applied feed rollers 70 adjusted longitudinally of the platen to positions where either one or the other will effectively coact with the narrow bill sheet, whether the latter be. inserted to overlie the ledger sheet, say, near one or the other side edge thereof, the entries'may be made as indicated above. Thus, a narrow billsheetand 1 accompanyingcarbon sheet may be inserted in proper correlation wit-h the ledger sheet, 'say, nearthe left-handedge thereof. A

single feed roller 0 coacting therewithmay which will now be described.

be applied to the bill sheet to hold it while i an entry is being written thereon and a manifold copy thereof produced near the left hand side of the ledger sheet. feed roller 70 may then be released and the bill sheet and its accompanying carbon sheet withdrawn and shifted to overlie the right hand side portion of the ledger sheet. The

The applied v 70' second feed roller 7 O at this" point may then 1 Q be applied to :hold the newly positioned "bill sheet and carbon sheet in place where the next entry will appear below the previously writ-' ten entry on the bill sheet, although such two entries will appearon the ledger sheet at difs V ferent points widthwise thereof, on, say, the c same cross line. However, it may for many purposes suffice to employ a single feed roller 70 separately applied and released in the manner hereinbefore described.

Forcertain purposes, or'in some instances,

where a plurality of feed rollers 70 are employed that may be individually adjusted to different positions longitudinally of the platen, as has been pointed out, it may be found desirable to c'ouple'said rollers together sothat they may be applied by a single operation. 7, Such a construction is shown in Figs. 12 and 13 wherein the finger piece'or rod 10 i may be lengthened and ex tend loosely through bearing openings in the toggle arms 101" of a plurality offeed rollers] 70, or of all of said feed rollers. "The rod may have detachably connected collars 141 at the ends thereof which prevent the accidental detachment of the rod from said tog- :gle arms but does not interfere with the independent adjustment of each of the supports 7 6 for the rollers 70, together with the parts Thus far we have described the means for carried bysuch support, longitudinally of efi'ecting an application of the feedrollers 69 and 70 to the platen and for withdrawing them from the platen, as well as the automatic control of theribbon vibrator, 17, the

defiector47, line indicator 60 and end stops by the, shifting of the feed rollers 69 under control of the finger piece 90, and also have described'the independent control of such parts by the finger pieces 59 and 126. However, in accordance with our present invention there remains a further and diflerent control of the partsunder certain conditions f A ssume that the partsare in the 3 position and that the ledger sheet L has been introduced rearwardly into channel 36 past the end stops 115.. It is desirable at this time to have the line indicator 60 in effective position, especiallywhen end stops such as are disclosed in said Hart application are not employed and the line indicator alone is depended on toproperly position the ledger sheet in a line feed direction. It also is desirable at this time that the introduced ledger sheet shall be lightly held against accidental displacement, but nevertheless is free from clamping e1 gagement of the coacting feed rollers 69 with the platen. In order to attain these ends it is merely necessary to shift the secondary finger piece rearward from the Fig. 3 position, to the position indicated in Fig. 4. The extent of this movement is determined by two stops 142 and 143 which are adjustably mounted on the inner face of the bracket plate Bland extend in the path of movement of the arm 57 and arrest it. Each of the stops 142 and 143 is in the nature of a screw stud having an eccent 'ic stem 144 (see Figs. 1, 4 and 5) that receives a bearing in an opening in the bracket plate 81 and extends freely therethrough to the outside of said plate where it is threaded to receive a binding nut 145 by which the associated stop 1 is held in the rotative position to which it may be adjusted.

The rearward shifting of the secondary finger piece 59 from the Fig. 3 to the Fig. 4 position not only results in shifting the deflector 47,- line indicator 60 and ribbon vibrator 1' from the Fig. 3 to the Fig. 4 position, but also results in the arm 5? coacting with the contact sleeve 140 so as to shift the links 134 and 136 rearward. a definite predetermined distance, determined by the arrest of the arm 57 by the stop 142, as shown in 4. This results in tending to restore the stops 115 under their spring pressure to normal position where they will bear lightly against the previously introduced ledger sheet and tend to hold it against accidental displacement. Such rearward shifting of the links 134 and 136 also results in displacing the arm 89 to the Fig. 4 position and in moving the feed rollers 69 close to but out of contact with the platen, as shown in Fig. 4. This is in order that the feed rollers may bear lightly against the ledger sheet without, however, clamping it against the platen so that the ledger sheet may if necessary receive accurate adjustment with the aid of the line indicator. At this time the parts will remain in the positions to which they have been shifted, leaving both hands of the operator free to adjust the ledger sheet. if this be necessary. After such adjustment is attained the operator moves the primary finger piece 90 rearward to the limit of its movement, thus applying t 1e feed rollers 69 to the platen and firmly clamping the ledger sheet in place. The finger piece 59 may now be moved forward and temporarily held in such position to condition the machine to receive'the sheets B and B which are gaged or positioned in a line feed direction by the end stops 115, which at this time are in effective position. After the sheets B and B are inserted and adjusted the feed roller or rollers are applied to hold them in position, the finger piece 59 is released and the machine is conditioned to proceed with the writing.

We prefer to employ a spring-pressed detent device to hold the finger piece 90 and the parts controlled thereby against accidental displacement from the Fig. 3 position, due primarily to the reaction of the spring 64 which is stressed at this time. This we attain by extending the arm 89 below the shaft 7 4 to provide an arm 146 having a dwell 147 at its lower edge that is concentric with the shaft 74 and also having an angular or flat retaining face or edge 148. A detent 149 is pivoted at 150 to the outer side of the bracket plate 81. I A coiled contraction spring 151 is connected at one end toa pin 152 on the plate 81 and is connected at the other-end to a pin on the tail end of the detent. The en'- gaging nose of the detent has a flat edge or face 153 which coacts with the face 148, as shown in Fig. 4, to retain the parts against accidental displacement under force of the spring 64. Rearward pressure exerted on either of the finger pieces 90'or 59'is, however, sufficient to disengage the detent against the reaction of its spring 151 after which the nose of the detent will ride on the dwell 147, as shown in Figs. 1 and 4.

From an inspection of Fig. 2 it will be understood that the inner sliding arm of the left-hand feed roller 69, when the latter is in effectiv position, constitutes a side edge gage for the sheets B andB. It will be understood, moreover, that when such sheets are introduced. the feed rollers 70 have been withdrawn from effective position, whereas, the feed rollers 69 have been applied to the ledger sheet, thereby conditioning the parts so that the arm 72- in question may properly function as a side edge gage for the sheets B and B. The fact that the support 76 for the left-h and feed roller69 (together with the parts carried by said support) is individually adjustable, enables the said arm 72, which acts as a side edge gage, to be adjusted to proper position to ooact with the sheets B and B.

Any suitable means may be employed other than the spacing blocks 34 and35 to act as side gages for the sheets R and R. In Fig. 2 we have shown a side gage 154 mounted on the spindle 67 for adjustment longitudinally thereof with the aid of a set screw 155.

One manner of using the devices of the present invention is as follows: 7

Assume that a register sheet R (Fig. 2) and its accompanying outside carbon sheet B have been introduced through the channel 37 and properly positioned with the leading edges thereof beneath their feed rollers .66, and that the remaining parts are in the Fig. 3 position. The operator then introduces a ledger sheet L from the front of the platen into the channel 36 and accurately adjusts or positions said sheet, with the aid of the line -indicator60 if desired, as hereinbefore indicated. After such adjustment of the ledger sheet an actuation of a finger piece 90 in'a rearward direction results in straightening the toggles for the rollers 69 to the Fig. 8 position and applying the feed rollers 69 against the platen and against the margins of the previously introduced ledger sheet. At this time the feed rollers '70 are in the released position, as shown in Fig. 8. The bill or statement sheet B with an accompanying carbon sheet B may then be introduced from the front of the platen into the channel 36, and

. between the feed rollers 7 0 and the platen,

or the ledger sheet thereon, as previously pointed out. After the statement sheet and the accompanying carbon sheet have been properly adjusted, with the aid of the end stops 115, the feed rollers 7 0 are shifted rearward by the operator from the Fig. 8 position. This results in applying said feed rollers to the previously adjusted bill or statementsheet B. The machine is then conditioned to proceed with the writing, and the matter written will be produced on the statement sheet and through the carbon sheets on the ledger and register sheets.

After the statement is written as described, the operator shifts the finger piece 90 to the Fig. 3 position, thereby releasing the feed rollers 69 and 70 and permitting ready withdrawal of the statement sheet, the accompanying, carbon sheet and the ledger sheet, and conditioning the machine to receive new sheets to replace those withdrawn.

If it be assumed that end stops, such as thosedisclosed in said Hartapplication, are employed, and that the parts are in the Fig. 3 position, then three operations of the parts are required to prepare the machine for making another entry, as follows 1st. Move the finger piece 90 to the Fig. 1 positionafter the ledger sheet is introduced.

2nd. Temporarily shift the parts controlled by thefinger piece 59 to the Fig. 3 position with the aid of said finger piece, and

3rd. Apply the feed roller or rollers 70 to the bill. sheet after it has been 7 introduced with the accompanying carbon sheet.

. The operator may then proceed with the writing.

,It will be understood that each of the feed rollers 70, its finger piece 104, its support 76, its actuating arm 106 and the intermediate connections bywhich said feed roller is actuated from said arm 106 and by the finger piece 104 may be detached from the remaining parts. Therefore, such parts maybe applied or omitted, depending on the use to which the machine is to be put, as atwo-sheet or three sheet biller, or for other uses such as have been hereinbefore indicated.

In substantially the same manner as hereinbefore pointed out the machine may be emmoved and new ones inserted, may constitute a register sheet, a proof sheet, a sales sheet, a distributing sheet, or a pay roll sheet, depending-on the use of the machine for different purposes.

In some instances the line indicator 60 may be employed to position, in a line feed direction, each sheet introduced from in front of the platen into the channel 36 when it is not feasible or desirable, for one reason or another, to employ end stops, or to employ end stops to coact with a sheet corresponding to the ledger'sheet.
